Detailed Description

Class for capturing mouse clicks.

This class handles mouse clicking functionalities integrated into the ImageDisplay. It uses a qt event filter to capture mouse clicks, handles image resizing and checks if the click was inside or outside the image. It also scales the pixel coordinates to get them w.r.t. the image (not the window) size. Mouse clicks image pixel coordinates are published as ros geometry_msgs PointStamped. The z component is ignored. The topic name where the mouse clicks are published is defined created after the subscribed image topic as: <image_topic>/mouse_click.
